CAW-HANDLING DEVICE.

Specification of Letters Patent.

Patented Aug'. 22, 1905.

Application filed August 25, 1902. Serial No. 120,934.

To all whom, t may concern,.-

Beit known that I,Jo1-IN V. ScHAnFER,a citi- Zen of the United States,residing at Chicago,

in the county of Cook and State of Illinois, have invented a certain newand useful Improvement in Car-Handling Devices, of which the following'is a specification.

My invention relates to car-handling devices, and particularly such asare intended for conveniently handling cars where loaded and empty carsare to be carried over inclined surfaces.

I have shown in my drawings, somewhat diagrammatically, oneform ofdevice in which my invention is made use of.

Figure 1 is a diagrammatic plan view. Fig. 2 is a diagrammaticlongitudinal section. Fig. 3 is a side elevation of a portion of thedriving mechanism. Fig. 4 is a part cross-section and elevation viewsubstantially on the line t 4, Fig. 3. Fig. 5 is a side elevation of thetrolley and spring-actuated pusher. Fig. 6 is a cross-section on theline 6 6 of Fig. Fig. 7 is an elevation of the trolley-carrying andfixed pusher.

Like parts are indicated by the same letter in all the figures.

A is the shed, for example, at the top of a mine from which the loadedcars'are had. A is the iioor of such shed.

B B are the rails of the two tracks, which in this case side by side runup a slight incline way from vthe receiving-shed and down along theincline to the delivei'y-ljioint.

C is the delivery-floor.

D D are the cars, in this case coal-cars.

E is an endless chain which passes through a suitable slot or betweenthe rails down under the iioors A and C.

Referring to Figs. 3 and 4, FF are suitable supporting-timbers, andmounted on them in a vertical position is the shaft F', carrying thesprocketwheel F2, around which travels the chain E. On this shaft is thegear-wheel F, meshing with the gear-wheel Fl on the shaft F 5, whichcarries the bevelgear F, meshing with the gear F7 on the shaft F, whichshaft carries the'driving-pulley F9 or may be driven by any desiredpower. F10 is a brake-wheel on the shaft F8, controlled by the lever-armF11, associated with the supporting-arm F12. By means of these severalparts the operation of the driving sprocketwheel may be controlled so asto drive the chain, and thus move the cars in any desired manner orspeed. The cars must be connected with the chain, and the mechanism forso doing' is shown in Figs. 5, 6, and 7. G is a trolley-link inserted inthe chain E and provided with down wardly-projecting parts G G at itsends. Each of these parts terminates in the piece G2, which is placed inopposition to a similar piece G3, on which latter piece is formed thebearing G'L for the axle G5, which carries the two trolley-wheels G G,adapted to run in the angle-iron rails G7 G7. The bearing GEt will beseen to be enlarged toward both its ends from the middle, so as to givethe trolley-axle G5 a certain amount of play. The parts G2 and G3 areheld together by the bolts Gs The trolley-link is inclosed by two blocksG9 G, which are held in position by the pins G10 G1, and on the outsideof these blocks rise the stops composed of the two side blocks G1l G,which are held together and pivoted on the cross-bolt G12 and by thecross-bolt G13. From this latter bolt proceeds the spiral spring G, itsother end being connected to the pieces G2 and G. The upper ends of theparts G1I are inclined, as indicated at G15. The stop is therefore freeto move at its upper end toward the right in opposition to the action ofthe spring G1* and is held from moving in the other direction by theengagement of the cross-pin G1 with the lower ends of the blocks GJ G".

In Fig'. 7 I have illustrated the fixed pushers. The several parts arethe same as those illustrated in Fig. 5, except such as relate to thepushers themselves. Here I show attached to the link G pushers J J,similarly shaped as the stops Gu G, but set on the chain in such a waythat the inclined faces J' of each faces in the opposite direction fromthe inclined faces G G15 on the stops Gu G11. The pushers J J aresecured in.position by the cross-bolts J2 J2.

The trolleys are placed along the chain alternately and are spaced sothat there is approximately one car length between each pair.

The cars D D are provided with the end cross-beams D DL and are mountedon the wheels D3 D3, which run on the tracks B B.

At the head of the shaft or in the shed A is mounted horizontallyasprocket-whecl K and around which the chain E travels. Thissprocket-wheel is mounted on the shaft K', which carries the pinion K2,and there may be at this end of the line a duplicate of the drivingmechanism at the other end of the line, or either end may have anydesired mechanism, or one end may have the driving mechanism and theother simply an idler to give the chain its proper direction.

I have not shown the rails, switches, &c., which extend beyond theendsof the chain E, as of course any desired arrangement of these parts canbe had.

I wish, as previously suggested, to have my drawings taken in thelargest possible sense as diagrammatic, and I wish it understood thatvarious figures of my device could be modilied without departing fromthe spirit of my invention.

The use and operation of my invention are as follows: Ie will assumethat the chain is traveling in the direction indicated in Fig. l, thatin Fig. 2 we are looking at the ascending side, and that the chain, withits trolley-pushers, is traveling as indicated by the arrows in Figs. 5and 7. Obviously the stops GH Gr1l will engage the first car pushed uponto the rails from the point where the chain with such pushers risethrough the floor C. The stops, however', will present to the beam D theinclined faces G15 G15; but the weight of the car will prevent itsmotion, causing the spring Grl4 to yield and allow the stops to descendand pass under the beams of the car and again assume their uprightposition, as indicated in the several drawings. Since the distancebetween the stops and the pushers of each pair is approximately equal tothe length of one of the cars, by the time this action has taken placethe fixed pushers J J will have reached the car and will engage its rearbeam D. The further motion of the chain will carry the car up theincline, as indicated in Fig. 2, and when the car begins to descend therear beam D will leave the pushers J J and the car will roll forwarduntil the forward beam D2 engages the stops G11 Gu, and the car byreason of its weight is held against the stops and continues its motionuntil it passes ofi' on the rails along the floor A. In like manner whenthe loaded cars are standing, for example, in the shed A in properposition and the chain is returning the action will be repeated, but inthis case the car will be carried up the short incline by the pusher andwill be sustained by the stop as it passes down the long incline. It isquite obvious that any irregularity of the ground over which the carsare to travel can thus be compensated and the cars can be controlledregardless thereof. In ordinary practice the loaded car is pushed ontothe track to a point just beyond where the chain and the trolleys comeup to the iioor and there the car stands. The first stop being hingedand held upright by the spring when it strikes the car is depressed andslips under the car and comes up in front of it. The pusher being' rigidengages the car by striking against its rear end and pushing it along.On the downgrade the car runs forward against the stop and is heldrigid. Thus the car is held between the pusher and the stop. hen thelower end is reached, the forward stop passes down through the iioor andthe car runs olf freely. I am enabled to bring about these results bythe association of the stops and the pushers, the stops being hinged orspring-actuated. I am also enabled in this manner to use a single chaininstead of using two chains with the fixed stops or pushers asheretofore.
